I don't see why you can't, or shouldn't, dedup an SSD. Deduping looks for identical sectors and frees one of them; since an SSD is completely random-access, there's no penalty for having some sectors far from the file's inode. Recopying an SSD is what makes no sense. Pierre -- sei do'anai mi'a djuno puze'e noroi nalselganse srera
